If you want to write pseudo-random data fast you may use one program
thread to create the random data with a PRNG and another thread which
writes the random data to disk at full speed. Have a look at
http://hungrycats.org/~zblaxell/projects/randstream/randstream.html

As for encrypting the swap, I choosed not to use any swap at all.
I have just bought more memory since it is so cheap.
